Subscribes to EventsStream and maps like-family events to
LikesRepository.refreshIds(). Cross-device likes (web flips a heart,
phone reflects it) now propagate without a manual refresh.
ProcessLifecycleOwner foreground hook re-runs the same refresh as
defensive cold-start cleanup — matches Flutter's resume-handler.
Screen-scoped events (playlist.deleted for a specific id, single-
request status_changed) intentionally NOT in the dispatcher; those
ride EventsStream.events directly from per-screen ViewModels in the
next commit.
